Need to be able to configure notification sounds (incoming call, text message, etc.)
We need some way to configure which sounds are played for particular events. For example, incoming phone call, incoming text message, alarm, etc.
The GNOME Settings application currently has no facility for configuring event sounds beyond the "alert" event.
Libcanberra and GSound are GNOME's APIs for playing sound event notifications. They make use of XDG Sound Theme and Naming Specifications. However, there seems to be no way to configure sounds for individual events beyond specifying a particular filename during play calls or modifying the sound theme. The XDG specs seem a bit static. It may be that another layer is needed on top of these APIs.
